Concerns with Xen PVH / HVMLite boot on Linux x86

I've been helping a bit with streamlining proper upstream support for Xen on x86 Linux. One of the items I have decided to take on is the so called "dead code" concern in theory present on x86 Linux Xen guests largely in part due to the radical way in which old PV Xen x86 Linux guests boot. This topic is a bit complex, so I had previously written two posts about this to help shed some light into these dark corners of the technical Linux universe that only a few really care about:Avoiding dead code: pv_ops is not the silver...

MirageOS Summer 2016 hack retreat roundup

Our first Cambridge-based MirageOS hack retreat took place yesterday - and what a fantastic day it was! The torrential rain may have halted our punting plans, but it didn't stop progress in the Old Library! Darwin College was a fantastic venue, complete with private islands linked by picturesque wooden bridges and an unwavering wifi connection. People naturally formed groups to work on similar projects, and we had a handful of brand new users keen to get started with OCaml and Mirage. The major tasks that emerged were: new hypervisor target: the integration of the Solo5 KVM-based hypervisor backend, bringing the number...

MirageOS Summer 2016 hack retreat announcement, and talk roundup

As summer starts to shine over an obstinately rainy England, we are organising the second MirageOS hack retreat in Cambridge! It will be held on Weds 13th July at the lovely Darwin College from 9am-11pm, with snacks, teas, coffees and a servery lunch provided (thanks to sponsorship from Docker and OCaml Labs). Anyone is welcome at all skill levels, but we'd appreciate you filling out the Doodle so that we can plan refreshments. We will be working on a variety of projects from improving ARM support, to continuous integration tests, the new Solo5 backend and improving the suite of protocol libraries. If you have something in...

TripleO QuickStart HA Setup && Keeping undercloud persistent between cold reboots

This post follows up http://lxer.com/module/newswire/view/230814/index.html and might work as timer saver unless status undecloud.qcow2 per http://artifacts.ci.centos.org/artifacts/rdo/images/mitaka/delorean/stable/ requires fresh installation to be done from scratch So, we intend to survive VIRTHOST cold reboot (downtime) and keep previous version of undercloud VM been able to bring it up avoiding build via quickstart.sh and restart procedure from logging into […]

RDO Triple0 QuickStart HA Setup on Intel Core i7-4790 Desktop (work in progress)

This post follows up https://www.linux.com/blog/rdo-triple0-quickstart-ha-setup-intel-core-i7-4790-desktop In meantime undercloud-install,undercloud-post-install (openstack undercloud install, openstack overcloud image upload ) are supposed to be performed during original run  `bash quickstart.sh –config /path-to/ha.yml $VIRTHOST` run. Neutron networks deployment on undercloud and HA Server’s configuration has been significantly rebuilt since 06/03/2016. I believe design bellow is close to proposed in https://remote-lab.net/rdo-manager-ha-openstack-deployment However […]
